Network Manager - Data Acquisition

Facilitates Real-time Supervisory Control of Power Stations Substations Key information points in a distributed power network

Development of Process Communication Interfacing RTUs, SA- and IED-systems Use of standardized protocols;

WAN instead of leased line to the station Deregulation leads to need for flexibility and versatility

IT-security Data Communications Redundant Solutions Enterprise Wide

PCU400 is the solution for Network Manager

RSP Address

Each Line Unit is assigned to a RSP address

The RSP address is unique within the Comport

The RSP address is the same for Line Unit A & B side

Every node in a RCS system must have an address

The RSP address is within range 1 .. 255. Typically the following intervals applies: [1..127] RTU lines

[128..199] Emulator lines

[200..255] Master Lines
